摘　　要：通过有限元仿真研究了整体陶瓷立铣刀的不同结构参数(周刃径向前角、周刃径向后角和螺旋角)对铣削力的影响,采用正交试验对刀具结构进行优化,对比分析了结构优化前后整体陶瓷立铣刀的铣削性能,并探究了刀具的磨损机理和失效形式。结果表明,优化后刀具的周刃径向前角为-8°,径向后角为10°,螺旋角为40°,结构优化后的刀具寿命提高42.9%,后刀面磨损量降低37%,工件已加工表面粗糙度降低5.5%;刀具的磨损机理主要为黏结磨损和扩散磨损,失效形式主要为剥落、微裂纹和崩刃,结构优化后的刀具磨损现象明显改善。In this paper,the influence of different structural parameters(radial rake angle of circumferential cutting edge,radial clearance angle of circumferential cutting edge and helix angle)of the solid ceramic end milling tool on the milling force is studied by finite element simulation.The tool structure is optimized by orthogonal test.The milling performance of the solid ceramic end milling tool before and after structural optimization is compared and analyzed,the wear mechanism and failure modes of the tool are explored.The results show that the radial rake angle of the optimized tool is-8°,the radial clearance angle is 10°,and the helix angle is 40°.The tool life after structural optimization is increased by 42.9%,the flank wear is reduced by 37%,and the machined surface roughness of the workpiece is reduced by 5.5%.The wear mechanism of the tool is mainly adhesive wear and diffusion wear,the failure modes are mainly spalling,micro-cracks and chipping.The tool wear phenomenon after structural optimization has been significantly improved.
